Abstract

The invention relates to a coal mining system and discloses a panel / tape zone coal pillar integrated coal mining system. The panel / tape zone coal pillar integrated coal mining system solves the problem that the existing roadway layout system has large coal pillar recovery difficulty. The panel / tape zone coal pillar integrated coal mining system is realized by A, setting a roadway protection coal pillar having width of 100m at the outer side of the original ventilation roadway and setting a roadway protection coal pillar having width of 20m at the outer side of the original transport roadway, B, arranging a stope face through normal mining processes and arranging a coal pillar recovery roadway in the roadway protection coal pillar outside the ventilation roadway, and C, after the stope face is completely exploited, arranging a coal pillar recovery work surface with width of 140m through the original ventilation roadway, the original rail roadway, the original transport roadway and the coal pillar recovery roadway, and recovering coal pillars between the transport roadway and the coal pillar recovery roadway through the combined mining technology. The panel / tape zone coal pillar integrated coal mining system is suitable for coal mining.

Description

technical field

[0001] The invention relates to a coal mining system for coal mining, in particular to a panel area / belt area coal pillar integrated mining system. Background technique

[0002] With the development of fully-mechanized mining and fully-mechanized excavation technology, coal mining is moving towards high-yield, high-efficiency, large-scale, centralization, and automation. The roadway layout system with coal pillars is widely used. However, due to the limitations of the roadway layout system, the recovery of coal pillars is very difficult. Therefore, in the actual mining process, coal pillars are basically not recovered or can only be partially recovered by old mining methods after mining, which not only causes waste of coal resources, but also affects subsequent coal mining. Based on this, it is necessary to invent a new coal mining system that can effectively utilize fully mechanized mining technology to recover coal pillars, so as to solve the problem of d...
